The Impact of the Samantha Academy of Creative Education (SACE) on Students Placed At-Risk at a Suburban High School in Southwest Texas
Get PDFReducing student dropout is of extreme importance to the United States. The loss
in revenue as well as in human terms is huge. Several problems exist concerning
students placed at-risk for dropping out. These include no agreed upon method of
calculating drop out rates, differing opinions on the causes of school dropout, and a
body of literature that is sparse concerning educational approaches for keeping
students placed at-risk in school. This study examined the impact of the Samantha
Academy of Creative Education (SACE) on the students placed at-risk and the
teacher perceptions of the SACE program by the teachers working in the program at a
suburban high school of Southwest Texas.
The population of this mixed-methods study consisted of secondary general
education students from a large suburban high school in Southwest Texas who had
been placed at-risk. One of these groups consisted of students that participated in the
SACE program while the other group consisted of a similar group of students not
participating in SACE. Statistical tests were conducted to determine if a difference existed between the two groups with regard to graduation rate, attendance rate, and
core grade average. Perceptions of the SACE program by the teachers that worked
within the SACE program were gathered.
Results indicate that student placed at-risk who participated in the SACE program
had higher core grade averages, higher rates of graduation, and higher rates of attendance
compared to students placed at-risk within the same high school who did not
participate in SACE. Teachers perceived that the SACE program was efficacious for
students placed at risk because of three broad themes. This study further demonstrated
that effective programs aimed at helping students placed at-risk can be
developed within the context of a regular high school setting. Recommendations for
further research and implications for practice were provided
Community College Student Engagement Patterns: A Typology Revealed Through Exploratory Cluster Analysis
Get PDFThis study employs survey data from the Center for Community College Student Engagement to examine the similarities and differences that exist across student-level domains in terms of student engagement in community colleges. In total, the sample used in the analysis pools data from 663 community colleges and includes more than 320,000 students. Using data-mining techniques to discover a parsimonious number of natural clusters and, in turn, a k-means cluster analysis as a means of revealing a naturally occurring typology of engagement patterns, our findings reveal that support service utilization is the most distinguishing feature of the similarities and dissimilarities across student groups, suggesting areas for further theory development and testing

New penicillin-producing Penicillium species and an overview of section Chrysogena
Get PDFSpecies classified in Penicillium sect. Chrysogena are primary soil-borne and the most well-known members are P. chrysogenum and P. nalgiovense. Penicillium chrysogenum has received much attention because of its role in the production on penicillin and as a contaminant of indoor environments and various food and feedstuffs. Another biotechnologically important species is P. nalgiovense, which is used as a fungal starter culture for the production of fermented meat products. Previous taxonomic studies often had conflicting species circumscriptions. Here, we present a multigene analysis, combined with phenotypic characters and extrolite data, demonstrating that sect. Chrysogena consists of 18 species. Six of these are newly described here (P. allii-sativi, P. desertorum, P. goetzii, P. halotolerans, P. tardochrysogenum, P. vanluykii) and P. lanoscoeruleum was found to be an older name for P. aethiopicum. Each species produces a unique extrolite profile. The species share phenotypic characters, such as good growth on CYA supplemented with 5 % NaCl, ter- or quarterverticillate branched conidiophores and short, ampulliform phialides (<9 μm). Conidial colours, production of ascomata and ascospores, shape and ornamentation of conidia and growth rates on other agar media are valuable for species identification. Eight species (P. allii-sativi, P. chrysogenum, P. dipodomyis, P. flavigenum, P. nalgiovense, P. rubens, P. tardochrysogenum and P. vanluykii) produce penicillin in culture

The manifold advantages of articulatory representations, Including microphone and speaker normalization
Get PDFI'm going to be making two broad points during my talk. The first is that we should do a transformation from speech acoustics to articulator positions as part of our speech processing. The second point I will try to make is that we can do a transformation from speech sounds to articulator positions
